CAR-FENDER.

Specification of Letters Patent.

Patented April 27', 1909.

Application tiled December 23, 1907. Serial No. 407,626.

Yo all whom it may concern: Be 1t known that l. FRANK A. Nansen, ot Minneapolis, Hennepin county, Minnesota,

haveinvented certain new and useful 11nprovenients in (lar-Fenders, ot which the tollowing is a specification.

My invention relatesl to tenders or lij'e guards ot the type i hown and described in my pending application No. tOi-5,004., tiled November 25, 1907, and the object ot the present invention is to simplify the mechanism of the operating parts and provide a .fender capable of beingl raised or lowered, 'but omitting the tolding ieature which 'forms an important parts'ot the ty'pe of fender shown in my other application.

The invention consists generally in .various constructions and combinations, all yas hereinafter described and particularly pointed ont in the claims.

1n the accompanying drawings. tol-ming i part of this specification, Figure 1 is' a side elewation of the forward portion of a car showing my invention applied thereto. ljig. 2 is a top view oi the same. Fig. B illustrates` th'el 'tender in its lowered or operative position. Fig. 4- is a front elevation showing the fender raised. Fig. 5 is a detail view ol one of the plungers which controls the vertical moven'ient of the fender. Fig. t3 is a sectional view illustrating a modified construction.

This invention is applicable to any type ot'v car, motor or engine and propelled it'rom any suitable motive power, and l do not in this appl1 ation, 'wish to be confined to the use oi the invention on a car ot' the type shown.

ln'the drawing, Q represents tl'ieft'orward portion of a street car on which the tender or car is n'iounted.

llhe 'tender ,2 consists ot a trarne, preterahly otgas pipe, supporting a wire fabric ft ol'l suitable mesh. rl`he rear rail oil the -trame is provided with plungers 5 that are \'ertically slidallle in cylinders (3 depending from the i"oi"\\'ard end oi" the car. Springs 7 with in said cylinders normally hold the p lungersy v in their raised position and the Vtender at the desired clevatrci from the track. Ar curved guard or butter iframe 7 having a suitable wire 'fabric 8 is vertically slidable between i guides t) on the front olthe car and is con- `nected with the fender frame by braces 10 .and is adapted to slide vertically therewith. This guard :trame has a door 11 through which access may be had to the draw bar when it is desired to attach two cars t'ogether.

For the purpose oi raising the fender, I provide links 12 pivotally connected to the rear rail of the fender at theirlower ends and at their upper ends attached pivotally to a coupling 13. Similar links 14 pivotally connect the said coupling with supports l5 on the under side of the car. The said coupling is pivotally attached to a piston 1.6 arranged within a -cylinder' 17 that is horizontally suspended under the car body7 saidV piston being normally held in one end of the cylinder by the tension of a. spring 18 provided .on the stem of said piston. When the fluid pressure is relieved 'in the cylinder 17, the piston spring will retract the piston, open the toggle joint. formed by the links li) and 14 and the springs within the cylinder (3 put under compression by the downward movement et' the fender, will raise it bodily out ot contact' with thc rails.

lt will be noted that this fender docs not tilt but has a vertical movement bodily from its operative to its inoperative position.

The lever lt) controlling the' tluid pressure Yif'or operating the brakes is mounted in the usual stand Q0 and is connected with the valve usually employed for regulating the tlow ot the brake operating tluid. A pipe i pipe and permits the brakes: to, he operated under nornml conditions without atlccting the vtender operating mechanism. VWhenever desir-cth however, the controlling lever may be set to allow the air to tlow through the pipe into the pipe 23 and from thence into the cylinder and operate the brakes simultantmusly with the lowering of the fender. The fluid pressure for the fender and brake cylinders is admitted from the i of the iender and norm-ill Y held in a iir-:i-

Rods conjected position by sprn :as 29.

arm 3l neet the 'rail 27 with slotted mounted on a valve S2 in the pipe 2i slotted connection ot.' the rods with. the arm 3l' alloivs the vertical movement of the fender. ln case the rail 2T contacts with an obstruction on the track, the arm 31 will be j oscillated and the valve opened to admit pressure fromfthe reservoir into the pipe 23 and to the fender and brake cylinders. The position assumed by thisl arm is indicated in Fig. 3, the rail Q7 being forced back against the fender to operate the said j.

arm and open thc valve.

ln Fig. 6 l have The f illustrated a modified construction Whichiconsists in inountin' the i operating cylinder 33 under the car directly over the fender and connecting the piston Ste the rear rail of the fender, a spring 35 normally holding the fender in its raised position. rlhe upper end of the cylinder connected to a pipe ,3G leading 4from the fluid pressure reservoir and through vwhich the pressure is admitted into the cylinder to force down the plunger and lower the fender to 'the track rails.

I claim as my invention:

l. The combination7 with a car, of a vertically sliding fender projecting in front of the same and supported at its rearend only thereon, a horizontal cylindeig suspended vfrom the car above and in the rear of said fender, a iuid' pressure service pipe con- .snected with said cylinder, a "piston for said cylinder anda lever mechanism connecting said piston and said fender.

2. The combination, with a'truck frame, of a vertically sliding fender and a Huidpressure-controlled mechanism for moving said fender to an operative position.

3. The combination, With a truck frame, of a fender supported thereon and having a vertically 'moving portion adapted to be raised above the track or depressedinto contact therewith, and iuid pressure controlled mechanism for depressingsaid fender.
